#2 Fix the problem that libvirt-cim can't find cdrom device that do not have disk
This patch would allow define a system with an empty CDROM device, and allow method
modify
resource settings to insert ISO files into an empty CDROM device.
Examples:
InvokeMethod(ModifyResourceSettings):
ResourceSettings: ['instance of KVM_DiskResourceAllocationSettingData {\nResourceType
= 17;\nInstanceID = "test/hdc";\nEmulatedType = 1;\nVirtualDevice =
"hdc";\nAddress = "";\n};']
InvokeMethod(ModifyResourceSettings):
ResourceSettings: ['instance of KVM_DiskResourceAllocationSettingData {\nResourceType
= 17;\nInstanceID = "test/hdc";\nEmulatedType = 1;\nVirtualDevice =
"hdc";\nAddress = "/var/lib/libvirt/images/test-disk.iso";\n};']
Note that the Address property should be set to "", not None(not set), to tell
that user want
an ejection.
#2 Add comments that saying what the code does, and improved some codes to avoid doing
duplicated things.
